Information: You can create your own color scheme and apply it to your entire presentation at once. Once you have created a color scheme, you can use it for future presentations.
1. In the top panel, find the "Design" > "Colours" > "Customise colours..."
2. In the window that opens, set the colours you want, the name of the scheme (this name will match the name of the XML file) and click the "Save" button. Your new colour scheme will be applied to all the slides in your presentation.
